A remote wireless monitoring terminal design, using ARM microprocessor as its core controller, is proposed in this paper. The whole system includes two sections. The first is the acquiring of physical signal design as monitoring terminal, which is composed of Blood Pressure Module, Blood Oxygen Module, ECG (Electrocardiogram), and respiration. The second is a method to achieve the function of remote monitoring based on 3G wireless network and SSH (Secure Shell). The whole software is run in embedded Linux system including driver and the corresponding applications. Experimental results showed that the design of telemonitoring system is reasonable, effective, meeting requirements basically.
